healthy new leaves can produce only sickly and stunted foliage, 

 the extent of the blighted area depending on whether the main 

 stem or only a branch was attacked. 



METHODS OF CONTROL. 



It should be understood that there is no known method of cur- 

 ing the disease, or of saving woodland once it has become thor- 

 oughly infested. The experience of other States has proved 

 this. Nor is it possible to save single trees, if badly diseased, 

 except at great expense, and even then the chance for failure is 

 great, owing to the impossibility of locating all the infected 

 spots. 



VIGOROUS MEASURES NEEDED IN EARLY STAGES. 



To check its spread at the beginning of its entrance into a 

 locality is, therefore, the only hope, and this hope is considered 

 a strong one by those who have studied the disease most. 



Dr. Haven Metcalf, who is the pathologist in charge of inves- 

 tigating this blight for the government Bureau of Plant Indus- 

 try, and who has spent a great deal of time in this work, states 

 that " in all cases we know of where the disease has been care- 

 fully eradicated, in localities where it has just appeared, the 

 work has been very successful; so that we feel warranted in 

 advising a very considerable outlay of energy to eradicate the 

 disease at the outset." 



METHODS OF ERADICATING. 

 Inspection of Nursery Stock. 



There are several ways of going about the eradication of the 

 blight. All chestnut nursery stock should be carefully inspected 

 for signs of the disease, as such stock has heretofore apparently 

 been one of the chief agencies of spreading the fungus. This 

 precaution should be taken by nurserymen and purchasers alike. 



Prompt Destruction of Diseased Trees. 



A careful inspection of trees for evidences of the disease 

 should be made by all owners of chestnut woodland during the 

 months of May and June, and any tree found infected should at
